Geological Summary

The Washiba-Kumonotaira volcano group consists of a cluster of small shield volcanoes with possible lava domes in a remote area in Chubu Sangaku National Park in the heart of the Northern Japan Alps. Iwagokekodani, an older Kumonotaira volcano was active from about 1-0.9 million years (Ma) . The younger Kumonotaira volcano was active about 0.3-0.1 Ma. Washiba-ike volcano is younger than 0.12 Ma (Nakano et al., 2001-). Hayakawa (2009 pers. comm.) indicated that the Washiba-ike explosion crater was formed in an area that post-dates the latest Pleistocene glaciation, and produced a tephra layer consisting of accretionary lapilli and fresh volcanic bombs.

The Global Volcanism Program is not aware of any Holocene eruptions from Washiba-Kumonotaira. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Washiba-Kumonotaira page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

Washiba-ike crater lies in the foreground with the dramatic granitic peaks of the Yari-Hodaka Range in the background to the south. The sharp-topped peak on the center horizon is Yariga-take (Spear Peak), a popular climbing destination in the Northern Japan Alps. The Washiba-Kumonotaira volcano group consists of a cluster of small shield volcanoes with possible lava domes in a remote area in the heart of the Northern Alps. A tephra layer from the Washiba-ike explosion crater overlies the 6300-year-old Akahoya Ash from Kikai volcano.

MODVOLC - HIGP MODIS Thermal Alert System Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
MIROVA Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.
